IMPROVEMENT IN LAMP-EXTINGUISHERS.

TO ALL WHQM IT MAY CONCERN:

Be it known that I, JAMES H. PRENTICE, of Ashtabula, in the county ofAshtabule, and State of Ohio,'have invented certain new and usefulImprovements in Safety-Lamp Burners; and I do hereby declare that thefollowing is a. full and complete description of the 'sarne,'reierencebeing had to the accompanying drawings, making apart of thisspecification, in which--. i

Figure 1 is a side view.

Figure 2 is a front view.

Figure 3 is a. top view.

Like letters of reference refer to like parts in the views.

In the drawing, A represents the burner and cap, which may beconstructed in the ordinary way.

3 represents a tube for the wick, near the top of which is hinged thecap or extinguisher C, which consists ofa curved metallic plate, made toreach from one side to the other of the tube, as shown in figs. 2 and 3.The object of this cup will be stated in the description. i

D is a yoke, extending round the tube, and connected to the cap; towhich yoke is attached the one end of the rod a, the otherextending'down into theglobe of the lamp, said end resting on a disk, 6.a

This disk is secured on the end of the rod E, the other end of said rodbeing prorided with a ball or weight, F, which rod and hell aresupported in the following manner:

Extending down from the under side of the tube l3 is'a stay, G, thelower end of which is bent at right angles, and which forms a kind ofuniversal joint, N, the section d of said joint, which is screwed on tothe rod E, moving in-the seat a. I i y I is a spring, to throw the capover the top of the tube.

The practical use of this improvement is as follows:

When the lamp is in use, the cap and its adjustments are in the positionshown in fig. 1. ',Now, if the lamp, when the cap is in this position,should be ,tipped or turned to one side, the weight on the end of therod IE will throw the disk from under the rod a, and, when thusrelieved, the spring I will force' the cap down on to the tube, asindicated by the dotted lined, thus extinguishing the flame. l

K is a lever for resetting the cap, which is done by depressing theouter end of said lever, thus lifting the rod a, and allowing the weightto fall back, bringing the rodE to a vertical position, and the-diskunder the end of said rod. By this means, the cup is reset, and willagain drop overthc tube, if thelarnp should be pushed or tipped tooneside.

'By the use of this cap and attachments, the danger caused by fire isavoided, for any jarring or shaking of the lamp will relieve the diskfrom the rod a, as described, and thus throw the cap over the'tube, andentinguish the flame before it can reach the oil that will be spilled bythetipping or shaking pfthe lamp.

The cap 0 can be thrown further back from thetube, more or less, asdesired, by screwing the rod E up through the section d of the jointwhich presses the disk 'against the end of the rod a, t hus throwing thecap back,- csmay be'desired.

What I claim as my improvement, and desire to secure by Letters Patent,is

1. The pendulum E, disk 6, in combination with the stem a, yoke D, andextinguisher O, substantially as and for the purpose set forth.

2. The screwpendulum E, stem at, and lever K, in combination with theyokeD, extinguisher 0, spring I, i

and tube B, substantially as and for the purpose set forth.
